这一环节的优势十分突出，技术垄断性强、行业集中度高，现金流稳定，风险相对较低——无论下游“淘金客”成败，都离不开硬件工具的支撑。但风险同样不容忽视：技术迭代可能颠覆现有硬件需求，且过度依赖资本循环，若下游融资断裂，订单规模或将大幅缩水。

"Your body feels great, it feels like a holiday," he told the BBC.
变化二：存储器需求，正在分层周期失灵的背后，是存储芯片需求端的结构性重塑。
The segmentation and paging scheme of x86 processors has been discussed extensively elsewhere (see the OSDev wiki, the Writing an OS in Rust series, or the Intel 386 Programmer's Reference Manual, Chapter 5). Here I'll focus on what the actual silicon does to make it fast.
